Mac Exhaust?
Anyone with a Mac catback out there? I'm looking into getting one, and I'm stuck between that and Flowmaster American Thunder. I'd like something loud and aggressive, but not as loud as the GMMG.
Sound clips, first hand accounts, anything would be appreciated.

Re: Mac Exhaust?
few months late on this, but i have the catback for our cars, it sounds nice on the stock L03 in my car without headers(getting those soon)
i had to be creative on sealing up the cat to the i-pipe,so I bought a doughnut gasket from advance auto(part no. 61089) pulled out the metal ring in the center and only used the gasket itself to seal the ball and socket from the cat to the i-pipe, worked like a charm
